Sustainable renovation of building envelopes

Abstract

Sustainable building is one of the important segments of sustainable development, and includes the use of building materials that are not harmful to the environment, then ensuring durability and energy efficiency in the design and use of the building and waste management from construction to demolition of buildings. Sustainable building implies seven principles, which must be considered from design, through construction work, and use and maintenance, and eventually demolition. In the last ten years, sustainable building principles and the standard of almost zero energy consumption - Net Zero Energy Building (NZEB) have been present in the European Union (EU) and beyond, in the construction of new buildings, while in Serbia and Bosnia and Herzegovina (B&H) they are still not present. Looking at the renovation of existing buildings, depending on the type of building and location, the NZEB standard is still not present even in the EU. In this research, the sustainable renovation of building envelopes (kindergarten and residential building) is presented and analyzed according to the NZEB standard of the country in the immediate surrounding, that is in the EU (Republic of Croatia), because the values of energy consumption parameters of the mentioned standard have not yet been defined in the territory of B&H and Serbia.
